Hinge Plate Assembly Blueprint - Custom Sidestand Bracket Drawing (Yamaha YZ450F)

This document is a black-and-white CAD-style line drawing (blueprint) titled "Hinge plate assembely" (sic). It shows an isometric view of a hinge plate assembly consisting of an angled, elongated bracket arm with a curved hook-shaped top end and a circular hole near its upper-middle section. Two flat square mounting plates are attached to the assembly: one near the upper right side and one at the lower end of the bracket arm, each with a single circular hole through its center. The drawing contains no dimensions, part numbers, material callouts, tolerances, or annotations beyond the title text. It appears to be one page of a multi-page fabrication drawing set (related files in the album include Baseplate, Plates, Sidestand, and Sidestandlift), likely documenting a homemade or custom sidestand/hinge mechanism. A reader can learn the general shape and configuration of the hinge plate assembly, how the bracket arm, hook end, and two drilled square plates fit together, but cannot derive measurements or hardware specifications from this page alone. The drawing does not identify any vehicle make, model, or year.
